CAR-TRUCK SIDE FRAME.

Application filed November The present invention relates to the construction of the side frame for a car truck which admits of the supporting of a jack upon a tie when it is required to elevate the frame to replace a worn bearing, or for other purpose irrespective ofthe position of the truck with reference to the jack.

A side frame of usual construction re quires the truck to be positioned, so that the journal box is in vertical line with a tie,

to admit of placing the jack upon a tie when it is required to lift the frame a bearing, or for other purpose.

In accordance with the present invention the ends of a side frame of a car truck have straight longitudinal under surfaces to admit of the jack engaging the same at differ ent points in the length of the surface while the jack is supported upon a tie, thereby obviating the necessity of moving the car to place the jack so that it may engage both a tie and the end of the frame when the latter is required to be elevated.

While the drawings ferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the many details of construction maybe resorted to within the scope of the invention as claimed, without departing from the spirit thereof. i

For a full umlerstandiug of the invention and the merits thereof, reference is to be had to the following descriptionand the drawings hereto attached, in which,--

Figure l is aside view of a car truck proto replace 'vided with a frame embodying the inven tion,

7 and Figure 3 is an enlarged sectional'view on the line 33 of Figure 1 looking in the direction of the arrows. r I

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

The side frame is of the general diamond shape and comprises an upper chordal member 1, a lower chordal member 2, side columns 3 connecting the chordal members and end journal boxes 4, the several parts being preferably of integral formation, although illustrate the pro-- per and lower members,

it is not essentialas the frame and its component parts may be of any determinate construction. The numeral 5 designates the usual bolster and 6 the springs resting upon the plank 7. Studs 8 project inwardly from the upper curved member 1 adjacent the upper ends of the bolster side columns 3 and have openings to receive the hooked ends'9 of brake hanger poltsl 10 which are supported in the mem- )QI A web 11 reinforces the joint formed between each of the journal boxes f and the adjacent end of the frame and these webs are disposed midway between the sides of I nal box. A straight surface 14 is provided at each end of the frame in line with the lower side of the ournal box and this is of such longitudinal extent as to rest upon a bolster supporting I side of each of the journal jack positioned upon a cross tie of the track when it is required to elevate the frame to replace a worn bearing or for any desired purpose.

Having thus described the invention, what I claim is: i

l. A car truck side frame comprising upper and lower members and intermediate connecting bolster side columns, the upper member having inwardly disposed studs and brake hanger bolts supported in said member and having their inner ends of hook form to enter openings in the said studs.

2. A car truck side framecomprisingup intermediate con.- nect-ingbolster side columns, and end journal boxes, the lower member having its end portions extending beyond the outer sides of the journal boxes in line with their bottom surfaces to provide extended-surfaces fora lifting jack whensupported upon a cross tie, webs between the outer sides of the journal boxes and the end extensions of r the lower .frame member, and other webs between the tops of the journal boxes and 7 upper frame member.
